For men and women alike, female anatomy can be daunting. To demystify a womans below-the-belt region, it helps to compare her pelvis to something less confusing. Allow me to introduce the three-room cottage analogy. The middle room is the vagina, bordered by the bladder in front and the rectum in back. All three rooms are separated by two vaginal walls. And at the top of the central room, perched like a chandlier in the ceiling, is the cervix, held in place by a pair of ligaments functioning like two strong support cables. These uterosacral ligaments connect the uterus at the level of the cervix to the front side of the sacrum. Projecting sideways from the top of the uterus, like two arms on a Mr. Potato-head, are the tubes and ovaries. Moving back down toward the foundation of the 3 room cottage sits a connective tissue wedge separating the vaginal opening from the anus this structure is called the perineum. At the level of the ground floor, these three rooms are surrounded by a wraparound terrace made up of levator ani muscles. You may know them as Kegel muscles. The Kegel muscles attach to the perineum something you can easily demonstrate yourself by using a mirror to watch the perineum retract with each Kegel contraction. Remember, this cozy, yet complex, house is just the INTERIOR, or pelvic, part of a womans anatomy. A closer look reveals that this house has quite the exterior. The vagina has two sets of vaginal lips: the labia majora, one on each side of the vaginal opening, with a pair of thinner inside lips called the labia minora resting between the labia majora. At the top of the labia minora is the clitoris, a small short tubular structure made of erectile tissue. The ultra-sensitive clitoris contains the highest density of sensory nerves of any human body part, many times more than the head of the male penis. The clitoris is covered and protected by the prepuce, or clitoral hood. During sexual arousal, the clitoris becomes erect and the prepuce retracts, making it more accessible.To learn more about female anatomy, from the importance of vaginal fitness, to disorders like pelvic organ prolapse, urinary and fecal incontinence, check out other videos on this site.

Think you're a vagina expert? Well here are five facts you've never heard before! Her hot spots have something very interesting in common with a shark! Vaginal lubricant is a melting pot of ingredients, from lactic acid to squalene, an ingredient also found in sharks' livers! But her natural lubrication isn't just for getting hot and heavy! Sex leaves women mentally alert because it takes them between 15 to 30 minutes to return to a pre-aroused state, while guys come down immediately. And how long does that sex take? According to studies, the average experience is 2 minutes and 50 seconds. Yet women generously rated these same sessions as "feeling" like 5 minutes and 30 seconds...so there's hope for the quickie!

A man's genital anatomy is much more than his penis. The male penis, which is the shaft that hangs outside of his body, generally lies limp. When arousal occurs and the penis fills with blood, however, it becomes erect. The testicles lie on either side of the penis. Their purpose is two-fold: To produce both sperm and the sexual hormone, testosterone. The testicles are surrounded by a thin membrane of skin called the scrotum. The scrotum acts as a temperature-control center for the testicles, keeping them slightly cooler than the rest of the body to ensure a pleasant climate for sperm. After the body produces sperm in the testicles, they are held in the epididymus, which is adjacent to the testicles, and then the sperm through a tube called the vas deferens. From the vas deferens, of course, the sperm travel to the penis to be ejaculated. The urethra is a tube that runs within the penis to transport urine and semen. And, surrounding the urethra at the penis's base, is the much talked about gland called the prostate. Although the prostate can be a source of pleasure, its reproductive purpose is to create a fluid that contains and nourishes sperm. This white, sticky fluid combines with sperm to create the ejaculatory substance known as semen. If you think the penis is complicated, though...check out all the parts that compose the vagina in our other videos!
